This phenomenon accelerated after a Compact of Free Association was signed between the FSM and the United States in 1986. Since then, the FSM has faced serious public health problems due to this new diet and other lifestyle changes. On small islands and atolls, imported foods and medicines may not arrive for more than a month if a typhoon or an oil crisis occurs. In this study, a detailed study of household food consumption is shown to represent the present situation of food security on Piis-Paneu Island (Chuuk Atoll, Chuuk State) and Pingelap Island (Pohnpei State). Keywords: banana, breadfruit, canned fish and meat, ethnobotany, MIRAB, root and tuber crops (Alocasia, Colocasia, Cyrtosperma, Xanthosoma, etc.) Introduction The Federated States of Micronesia (FSM) consists of four states (Yap, Chuuk, Pohnpei, and Kosrae, from west to east) composed of approximately 600 small islands, which amount to an area of approximately 700 km2. However, the FSM is spread over more than 2,600,000 km2 of the Pacific Ocean and spans approximately 2,500 km from east to west. In the 1950s people in the FSM still ate a “traditional” diet based on starchy staple crops (e.g., breadfruit, tuber and root crops, banana, etc.) and marine resources (e.g., fish, octopus, clams, turtles, etc.) (MURAI 1954), but this began to be replaced by a diet rich in rice, flour, sugar, fatty foods, and other imported or processed foods after the United States Department of Agriculture started its supplementary feeding program in the 1960s (ENGLBERGER et al. 2003). This phenomenon accelerated after a Compact of Free Association was signed between the FSM and the United States in 1986 (HEZEL 2004). Since then, the FSM has faced serious YAMAMOTO Sota public health problems due to this new diet and other lifestyle changes, and the government, non-governmental organizations (NGOs), and researchers have attempted to promote a return to local foods because of their higher carotenoid and vitamin contents compared to modern foods (e.g., ENGLBERGER et al. 2009). However, the outlook for these programs is still bleak. In the present paper, a detailed study of household food consumption is shown to represent the present situation of food security in Piis-Paneu Island, Chuuk Atoll, Chuuk State and Pingelap Island, Pingelap Atoll, Pohnpei State, the FSM. This paper includes results of presented papers at “Research and Education linkage between Pattimura University and Kagoshima University”, at “the 113th and the 116th annual meeting of Japanese Society for Tropical Agriculture”, at “the ISISA Islands of the World XIII”, and at “the 9th International Conference on Small Island Cultures.” Materials and Methods Food consumption survey was conducted to three households in Piis-Paneu Island from September 2012 to August 2013 and to two households in Pingelap Island from August 2012 to January 2014 with Questionnaire sheets (Fig. 1). These households were selected to survey dietary patterns because of an average family size and income. Questionnaire items are as follows: starchy staples (rice, breadfruit, Cyrtosperma merkusii, banana, others), marine resources (fresh fish, dried fish, canned fish, others), meat (fresh, canned), others (instant noodle, coconut, vegetable, fruit). Frequency of each item in one month is calculated using a following formula: Frequency (%) = (total number of appearances of each item / total number of meals in one month) × 100. Results and Discussions Imported food (rice, canned fish and meat, instant noodles, etc.) Rice consumption of households in Piis-Paneu Island is very high (PIS-A: 99.3%, PIS-B: 96.3%, PIS-C: 72.1%, 12-month average) compared to that in Pingelap Island (PLP-A: 65.7%, PLP-B: 33.2%, 18-month average) (Table 1). Households in Piis-Paneu Island also used imported food more frequently than those in Pingelap Island, e.g., canned fish (PIS-A: 78.3%, PIS-B: 34.6%, PIS-C: 23.4%, PLP-A: 2.8%, PLP-B: 1.0%), canned meat (PIS-A: 52.1%, PIS-B: 2.3%, PIS-C: 8.1%, PLP-A: 1.4%, PLP-B: 0.5%), and instant noodles (PIS-A: 87.4%, PIS-B: 51.2%, PIS-C: 43.1%, PLP-A: 22.5%, PLP-B: 9.9%). This is partly because of the limited access to Pingelap Atoll. Villagers in Pingelap Island said that a public ship operated 2 Food Security in Small Islands: Case Studies in the Federated States of Micronesia Pingelap Atoll 1km Deke I.

There is a 300 m airstrip in Pingelap Island, and Caroline Islands Air serves a light aircraft (for eight persons) to the island, but a flight schedules is irregular and one way costs USD 190. If people would like to send some stuff to Pingelap Island via Caroline Islands Air, it costs USD 0.75 per pound, which is very expensive to villagers. Compared to Pingelap Island, people in Piis-Paneu Island can easily access to Weno Island, the main island of Chuuk Atoll, and buy any kind of imported food there. Local food (breadfruit, root and tuber crops, marine resources, etc.) All households in Piis-Paneu and Pingelap islands ate fruits of breadfruit with high frequency in especially May to September because of the seasonality of breadfruit. Preserved breadfruit was also used. If they cannot get breadfruit, they ate banana and/or Cyrtosperma merkusii. The frequency of use of marine resources was not very different among months; fresh fish (PIS-A: 81.1%, PIS-B: 68.5%, PIS-C: 69.2%, PLP-A: 67.4%, PLP-B: 54.9%), dried fish (PIS-A: 42.9%, PIS-B: 34.1%, PIS-C: 33.4%, PLP-A: 0.2%, PLP-B: 0.1%), and other marine resources such as clam, octopus, land crab, sea turtle etc. (PIS-A: 42.1%, PIS-B: 12.2%, PIS-C: 29.0%, PLP-A: 1.2%, PLP-B: 4.7%). Good candidates for food security crops It is found that people in two islands still use crops and marine resources obtained from the island (or atoll) with high frequency. However, people in Piis-Paneu and Pingelap islands somewhat depended on the imported rice. Moreover, the frequency of other imported food such as canned fish, canned meat, and instant noodles was high in Piis-Paneu Island. On small islands and atolls, imported foods and medicines may not arrive for more than a month if a typhoon or an oil crisis occurs. Therefore, it is very important to re-discover plants already naturalized on each island, for food security. From this perspective, Alocasia macrorrhizos and Tacca leontopetaloides are a very important starchy crop for emergency in Piis-Paneu and Pingelap islands. However, a young generation has never eaten them and/or does not know how to cook (Fig. 2). It is necessary to document how to eat these plants for the next generation. One more important candidate plant for food security is chili peppers (Capsicum frutescens), which can serve not only as a spice (fruits) but also as a vegetable (leaves) rich in carotenoids and vitamins (RESOURCES COUNCIL OF THE SCIENCE AND TECHNOLOGY AGENCY 2001). People in Piis-Paneu and Pingelap islands don’t often eat vegetables (PIS-A: 67.9%, PIS-B: 0.5%, PIS-C: 16.5%, PLP-A: 1.2%, PLP-B: 0.1%).
